To'all whom it may 0mm,-

Be it known that I, JAMES GOWER, 0f Iron-. ton, Lawrence county, "Ohio, have inventednew and useful'ltolls i or Maki n g Three-Headed Railroad-Rails; and I do hereby declare the following 120 bea full, clear, aml exaot description 'thereof, reference being had to-the accom- -1 take a Emmett number ofyslabs'to build up an ordinary square or-r'eetangular pile about seven inches broad by eight inches high. The

first two passes, 1 and 2, serve to compact the pile. I commence forming my rail in thethird and fourth passes, -3, and 4, of myroughing-- rolls,as the present ordinary Trail is formed.

The following passes-4o wit, 5, 6, 7 and 8- of my roughing-rolls serve to compact and elongate the pile, and to cause it to approximate the form suitable for introduction to the finishing-rolls. In the first and second passes, Y

9 an d '10, of the finishing-rolls twoof the three heads have begun to be: formed. In the grooves forpasses Nos. 1L and 12 are secured stationary mandrels A .A', which, occupying the channel "hetweel'i the two already-formed heads preventtheir beingcrowded together (luring the-formation of the'third and remainjing head, which takes place at passes '11 and .12.- From passes 12 to 13 the pile is turned' one-fourth around, and-thence through passes 14-13017, inclusive, it is turned one-third around eachtime, Passes 15 and 17 are made ,in the same direction and through the same-groove,- but witha different presentation of the ind ividual heads each time, -,I claim hereiuas new and of pryinvention- The arrangement of rolls',-Fig's. 1 and 2, and

mandrels A A, or their equivalents, for the. manufacture of three-headed.railroad-rails, substautially. as set forth.

In testimony of which invention I hereunto set-my hand. I I
